目前地理课利用一些教具、模型,在课堂上进行演示,是对学生进行直观教学的有效方法。现介绍在《高中地理》上册教学中的几个演示。 地球公转引起太阳直射点、正午太阳高度角和昼夜长短变化的演示。在讲台中心放一球表示太阳,讲台边缘放地球仪表示地球,用一橡皮圈套住地球仪表示晨昏线,用一小木条表示太阳光线。按逆时针方向不 At present, geography courses use some teaching aids and models to demonstrate in the classroom, which is an effective way to teach students intuitively. Now introduce several demonstrations in the “geography of high school” teaching. Earth’s revolution causes a demonstration of changes in the sun’s direct point, midday sun elevation, and day and night. Put a ball in the center of the podium to indicate the sun. Put a globe on the edge of the podium to represent the earth. Use a rubber band to cover the globe to indicate the twilight line and a small wooden bar to indicate the sun’s rays. Not counterclockwise
